CVE-2024-8918: file manager vulnerability

What is known

The File Manager Pro plugin for WordPress is vulnerable to Limited JavaScript File Upload in all versions up to, and including, 8.3.9. This is due to a lack of proper checks on allowed file types. This makes it possible for unauthenticated attackers, with permissions granted by an administrator, to upload .css and .js files, which could lead to Stored Cross-Site Scripting.

Business impact

Successful exploitation of CVE-2024-8918, a high vulnerability (CVSS 7.4) affecting file manager, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether file manager is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
